Background / History

Nanamo is the daughter of Nereus and Charlotte Linlin, born before Perospero as Linlin's true eldest child. She inherited Linlin's exceptionally durable “Steel Balloon” talent, but was raised primarily by Nereus after her parents separated over incompatible values and continued to dispute her custody. Although she visits and cares about her Charlotte half-siblings, she is notably more comfortable living with Nereus. 2 15 16

Linlin gave Nanamo Hermes, a high-caliber cloud Homie formed from a portion of her own soul, as both a gift and protection. Nanamo grew up on Beehive Island, where Nereus ran a tavern; even as a child, she managed its damages ledger and tried to overcharge Kaido for repairs to fund an outing with Katakuri. 1 11

When the Fat Bottle Pirates injured Brulee and Pudding, Nanamo asserted her status as the eldest sister and joined Katakuri in retaliating. She helped annihilate the crew, then immediately searched their base for treasure to split with Hermes. 12 14 15

Nereus later became ruler of Fish-Man Island, making Nanamo its legal first heir. She assists with population records, military recruitment, pirate-entry administration, diplomacy, and commercial projects, though her interest in the treasury often exceeds her interest in formal succession. 80 82 85 208

Appearance

Nanamo is petite despite being the daughter of two unusually large parents. At age seventeen, she had only recently surpassed 1.5 meters in height and looked little different from her childhood appearance. 132

• Possesses seemingly delicate skin that weapons and ordinary attacks fail to damage. 14
• Usually accompanied by Hermes, her sentient cloud Homie. 11
• Is recognized publicly as a princess of the Ryugu Kingdom. 80 279

Personality

Nanamo is playful, outspoken, and deeply attached to money. She enjoys counting treasure, calculating compensation, collecting bounties, and finding business opportunities in disasters or pirate traffic. However, she distinguishes legitimate earnings from exploiting supporters: she forced a Fish-Man Island food vendor to accept payment rather than accept free food because of her status. 15 36 52 90 208

Despite her casual attitude toward work and training, she takes responsibility seriously when family, subordinates, or protected territories are threatened. She led the response to attacks on her siblings, confronted Ochoku alone in the deep sea, protected Dressrosa from the Donquixote Family, and handled Shakky's business return professionally. 12 198 211 320

Nanamo dislikes being called a monster and is confident in her own strength. She is also sensitive about her lack of physical growth, while Hermes worries far more than she does about her status as heir. 14 132 153

Abilities & Skills

Fish-Man Physiology

Nanamo has the natural physical advantages of a Fish-Man, including arm strength stated to be ten times that of an average human.

• Held a pirate captain's sword motionless in her palm and crushed the blade through raw grip strength. 14
• Can operate freely in the deep sea, where she confronted Ochoku without support. 198
• Her inherent durability allows her to withstand bullets, explosions, and powerful attacks without using Haki defensively. 14 321

Steel Balloon

Nanamo inherited Charlotte Linlin's “Steel Balloon” talent, granting extraordinary natural toughness.

• Katakuri believed he could not break through her defense while still growing. 16
• A sword could not mark her skin even under pressure. 14
• Donquixote Family attacks, including explosions and gunfire, failed to injure her. 320 321

Corrosive Secretion

Nanamo's Fish-Man lineage grants her the ability to produce highly corrosive liquid, strengthened enough to corrode metal.

• Uses acid-infused water needles to kill or severely corrode opponents. 14
• The ability is innate rather than Devil Fruit-based. 14

Fish-Man Karate

Nanamo practices Fish-Man Karate, including long-range water-based attacks and shockwave techniques.

• Uchimizu: Acid Rain — Fires a shotgun-like barrage of acid-laced water needles that pierce targets and continue into surrounding structures. 14
• Karakusagawara Seiken — Produces a shockwave punch used to repel Trebol's mucus. 320
• Combines Fish-Man Karate with Giant techniques for large-scale attacks. 138 320

Elbaf Spear

Nanamo employs techniques derived from the Giant Race's Elbaf Spear and adapted through Fish-Man Karate.

• Elbaf Spear: Sea Roar — A destructive punch that creates ripples and water fluctuations; used against Kozuki Oden and to pulverize Pica's massive stone body. 137 320
• Azure Bind and Dragon Fang Pierce — Follow-up techniques used to defeat Oden. 138
• Particularly effective against huge targets and structures. 320

Haki

Nereus personally trained Nanamo in Haki alongside Amphitrite.

• Uses Observation Haki to assess hidden opponents, such as locating Pica's true body within his stone giant. 320

Equipment / Weapons / Items

• Hermes — A top-tier cloud Homie created from Charlotte Linlin's soul; serves as transport, bodyguard, assistant, and combat partner. 11

• Treasure and accounting records — Frequently maintains or reviews financial records and spoils. 1 36 265

Relationships

• Nereus — Father, instructor, and ruler of Fish-Man Island. Nanamo is closer to him than to Linlin, and he protects her from major dangers while preparing her for future leadership. 1 16 59
• Charlotte Linlin — Mother. Linlin values Nanamo highly as her first child and Steel Balloon heir, but their relationship is strained by Linlin's possessiveness and Nanamo's choice to live with Nereus. 2 16 188
• Hermes — Her loyal cloud Homie and closest attendant. Hermes assists in travel, combat, bookkeeping, and constant advice—often unwanted. 11 71 132
• Katakuri — Younger half-brother and combat partner. They retaliated together against the Fat Bottle Pirates, and Katakuri respects her superior defense. 12 15 16
• Brulee and Pudding — Younger half-sisters whom Nanamo defended after the Fat Bottle Pirates attacked them. 12
• Chloe — Younger sister. Nanamo is protective of Chloe and works with her during travels and conflicts. 175 251 253

• Scarlet — Friend and Princess of Dressrosa. Nanamo assists Scarlet with personal problems and later supports Dressrosa's recovery and commercial development. 87 251 328
• Tesoro — Trusted commercial subordinate. Nanamo approved his promotion to manage external revenue in the Sabaody region. 272
• Kaido — Longtime acquaintance from Beehive Island. Nanamo regularly teases him over unpaid damages and can fight him without intimidation. 1 258

Trivia

• Nanamo's existence delayed Perospero's birth and indirectly prevented the birth of Charlotte Compote in this timeline. 2
• Totto Land treats mentioning Nanamo as a serious violation of Big Mom's rules, and old images of her have been obscured or removed. 188
• Her former bounty was heavily inflated by Nereus's influence. 320
• She prefers pirate-entry work partly because captured pirates can be exchanged for bounty money. 338
